What does HBO Max error code 303 mean?
Error code 303 on HBO Max (now Max) is an Apple TV-specific error that indicates a problem with the app's connection to HBO Max's servers or with your account authentication on that device. It can be caused by a glitched app session, an outdated app or tvOS version, a subscription issue, or a temporary server outage.
Why does HBO Max error 303 only happen on my Apple TV?
Error 303 is most commonly reported on Apple TV because it relates to how the HBO Max channel integrates with the tvOS platform.

Will deleting and reinstalling HBO Max fix error 303?
Yes, in many cases deleting and reinstalling the Max app on Apple TV resolves error 303 by clearing corrupted cache data and replacing the app with a fresh installation. After reinstalling, make sure to sign back in with your HBO Max or Max credentials.
Does HBO Max error 303 mean my subscription is cancelled?
